Application filed September 14, 1925. Serial No. 56,409.

The present invention relates to. a milk meter which is adapted-to be utilized in a pipe line for milk such as is used around dairies and the like 'for measuring the amount of milk passingtherethrough.

An important object ofthe invention is to provide a meter of this nature whereinthe propelling unit is capableof being ea slly and quickly assembled or disassembled for cleaning purposes.

Another important object of the inventlon is to provide a highly novel propelling unit in a meter which possesses a revolving motion and an oscillatory motion about its own axis.

Another important object of-the invention is to provide an improved propelling unit in a milk meter which is simple'in its construction, durable,'thoroughly reliable and efficientin operation, not likely easy to become out of order, and otherwise well adapted to the purpose for which it is designed.

Vith the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and 1n the combination and arrangement of parts as will'be hereinaftermore fully described and claimed.

In the drawing, V

Figure 1 is a side elevation of the milk meterembodying the features of'my inventlon, v

Fig. 2 is a verticallongitudinal section therethrough,

Fig. 3 is atop plan view of the pr'opelling unit with the cover plates removed showing the propeller in different positions,

F '4 is a similar view showing the pro peller in still further different positions,

Fig. 5 is a plan view of the cover forthe propelling unit,

Fig. 6is a side elevation thereof,

Fig. 7 is a plan view of the propeller, and

Fig. 8 is a sectional view thereof.

Referring to the drawing in detail, it will be seen that numeral 5 designates the casing which ismounted on the base 6 by means of bolts 7 or in any other suitable detachable manner. The base 6 is of a hollow construction and has a conduit 8 leading to the interior thereof from the inlet 9 which is formed integral with the casing 5. An outlet 10 is oppositely disposed from the inlet'9 and communicates with the interior of-the casing as will be apparent from an inspection of Fig. 2. V i a The propelling unitincludes a shell formed by the shelf or bottom 11 resting on shoulders 12 interiorly of the base 6, an outer circular wall 13, an innercircular wall 14 concentrically disposed in relation to the outer wall and shorter in height than the outer wall, a cover 15 having a depending circular wall 16 concentric with the wall 14 and an upwardly extending circular wall 17. a

'A. lug 18' rises from the center of the bottom 11 and is disposed centrally of'the Wall 14 so as to form a circular path thereabout.

A propeller A is mounted in the shell. Referring specifically to this propeller as illustrated to advantage in Figs. 7 and 8, it "will be seen that 19 designates. a. circular plate having a rim 20 disposed thereabout. The plate and rim 20;are provided with'the radially extending slot 21. The plate 19'is provided with arcuate slots 22 disposed concentrically about the center of the plate. A pin 23 depends-from the center ofthe plate 19 and a pin 24 rises from the center of the the circular path provided by the wall 14 move between the upper edge of the wall 14 and. the loweredge of the wall 16 as is ap-' parent from an. inspection of Fig. 2.

The rim 20 is adapted to move within the space between walls 14 and 16 and wall 13. A partition 25 is disposed between walls 14 and 16 and wall 13 and extends radially. This partition further extends between the bottom 11 and the cover 15. The partition also extendsinto the slot 21 of the propeller A. An opening 26'is rovided in the bottom 11 to one side of t e partition 25, and an opening'27 is provided in the cover 15 to the other side of the partition 25. The milk if about the lug 18. The plate 19 is adapted to V between one-half of the rim 20 and approximately one-half of the wall 13 thereby tending to move the propeller to the dotted line position shown in Fig. 3, at which time the pin 23 has moved t-hrough an arc ofv 90 about the lug'18, and the rim and plate 20 .Fig. 4-, the movement of the milk .andl9 respectively have slightly oscillated about the axis "of the'pin because of the engagement of the partition in the slot 21. The space just mentioned has enlarged and has a tendency to continue to-enlarge as the milk further flows thereinto, thereby foreing the propeller to the full line position shown in Fig. 1. When in this position, the .pin 23 has moved through an arc of 180 from its initial position about the lug 18.

When in this position, the milk flows'inside of the rim, thru the slots 22, and out the opening 27, the slot .22 being provided for the'purpose of allowing the liquid to pass into' the space above the plate so that the 1 capacity of stantially equal to that of the outer chamthe inner chamber will be subber. I v i 1 When in the full line position shown. in

as described tendsto move the propeller to the dot-ted line position shownin thesame figure at which time the. pin 23 has progressed to 270 from its initial position about the lug 18. From this position, the propeller will be returned to its initial position as will be obvious.

A housing 30 for shaft 31 depends from the plate 32. which shutsoif the upper portion of the casing from the lower portion. 'Thehou'sing 30 is recessed at its bottom end for receiving the wall 17- and'a packing nut 34 is engaged on the housing within the recess for holding the packing 35 about the shaft 31'; A. partition 36 is disposed in the casing above the plate 32 and the upper end mounted a cross head'or crank 43 engageable by the pin 24, so that when the propeller A moves as heretofore described, this pin which moves in a circular orbit will turn the crank 43 to' impart rotary motion to the shaft '31. This rotarymotion of the shaft 31 imparts rotary motion to the shaft 37 the above description.

projecting through. the intermediacy of the gearing 38 and thus the counting mechanism 41 is operated through the gears 39 and 40.

It will be seen that this device is capable ofbeing placedin a pipe line through which milk flows for the purpose of measuring the milk. The invention, however, is in no way limited to this particular use and may be adapted to measure any flowing liquid.

The present embodiment of the invention has been disclosed merely by way of exam-,

ple since in actual practice it' attains the features of advantage enumerated as desirable in the statementof the invention and It will be apparent that numerous changes in the details ofconstruction, and in thecombination and ar-.

rangement of parts may be resorted to with- .out departing from the spirit or scope of:

the invention as hereinafter claimed, or sacrilicing any of its advantages' Having thus described my invention, what I claim as new is:'' 1

In a milk meter, a shell formed with .an inlet and an outlet, shoulders formed in the shell, a casing having inner and outer concentric circular walls and top and bottom walls, said bottom wall projecting beyond the outer circular wall and resting on the shoulders to dispose the casing between the inlet and the outlet, a partition disposed radially between the circular walls and'between the top and bottom walls,said casing havingfan opening in its top to one side of the partition and another opening. in its bottom to the other side of the partition, a

propeller including a circular plate having a radially disposed slot extending inwardly from its edge, a runabout the outer edge said inner circular wall being formed intop and bottom sections disposed in spacedrelation to accommodate said plate therebetween, said plate being provided'with slots to allow liquid to-pass into'the space above the plate, 'a lug rising from the bottom of the casing centrally of the inner wall,-a pin downwardly and centrally from the plateto move in a circular orbit about the lug within the inner wall, said rim being of such length as to engage said top and hotand having a slot at the slot of the plate, 7

tom walls to form therewith and with the concentric circular walls a measuring chamber, said partition extending into the slot of the plate and the rim, a second pin project ing upwardly from the center oftheplate, a shaft, a crank on the shaft engaged by the second pin, and a counter mechanism operatively connected :with the shaft.

In testimony whereof I aflix mysignature.
